250HP Workover Rig

250HP Workover Rig,Well Service Rig, China Service Rigs Supplier oilfield equipment by ZYT Petroleum Machinery
The **250HP workover rig** is a medium-duty, truck-mounted well servicing unit built for moderate-depth workover operations up to 3,600 meters. Featuring a 6×6 off-road chassis, it delivers the mobility needed for remote well sites while maintaining a practical hook load of 675 kN. This well service rig is designed for oilfield service companies that operate in challenging terrain — where paved roads end and rough wellsite tracks begin. The 6×6 chassis provides excellent traction on mud, sand, and uneven ground, reducing mobilization delays when moving between scattered well locations. With optional 21m or 23.5m telescopic mast heights and single or double drum drawworks configurations, this service rig adapts to a wide range of well servicing tasks — from routine tubing pulls to more complex fishing operations on medium-depth wells.

Features

1. **6×6 Off-Road Chassis** Built on a purpose-built 6×6 heavy-duty truck chassis with excellent off-road capability. Handles rough wellsite tracks, muddy access roads, and remote locations that 4×2 chassis rigs struggle to reach. 2. **Hydraulic Mechanical Transmission** High-speed diesel engine paired with hydraulic transmission box delivers smooth, flexible power delivery with high starting torque. Stepless speed adjustment makes operation simple for crews of varying experience levels. 3. **Optional Mast Configurations** Choose between 21m or 23.5m two-section telescopic mast heights to match your well servicing requirements. A simple drilling platform is also available as an option for light drilling or workover combined operations. 4. **Flexible Drawworks Options** Single drum or double drum drawworks available. The main drum features an integral LEUBS groove for optimal wire rope spooling, equipped with a pneumatic anti-collision device for safe operation. 5. **675 kN Hook Load Rating** Rated for 675 kN maximum hook load with 6-line φ22mm wire rope arrangement. Designed for workover operations on wells up to 3,600m depth, with 2-7/8 inch (73mm) tubing as the standard pipe size.

Applications

The 250HP workover rig is engineered for medium-depth workover operations on oil and water wells up to 3,600 meters. It's a versatile all-rounder that handles both routine maintenance and more demanding well intervention tasks.

- Primary use: tubing and rod pulling on medium-depth producing wells, pump changes, and well cleanout operations.
- Ideal for service companies operating in remote areas with challenging access roads, thanks to its 6×6 off-road chassis.
- Commonly used in onshore oilfields across the Middle East, Central Asia, Russia, and Southeast Asia.

Built for Remote Well Sites

What sets this 250HP service rig apart from lighter 4×2 units is its 6×6 chassis capability. When well sites are accessed via rough desert tracks, muddy field roads, or mountainous terrain, the 6×6 drivetrain gets you to location reliably — no waiting for road repairs or additional towing support.

The rig's hydraulic system and drawworks are sized for full 10-hour shifts of continuous work. Whether you're pulling tubing all day or handling a stuck pipe situation, the components are engineered to keep going without overheating or fatigue.

Optional double drum configuration lets you run a sand line or auxiliary line alongside the main hoist — useful for fishing operations, bailer work, and other interventions that require two independent lines.

Choosing the Right Workover Rig Size

For wells between 1,500m and 3,600m depth with standard 2-7/8 inch tubing, the 250HP unit hits the sweet spot: enough hook load to handle most workover tasks, without the higher operating cost of a larger rig.

If your wells regularly have stuck pipe issues, heavier scale, or you need to run 3-1/2 inch tubing, consider stepping up to a 350HP Workover Rig for extra pulling capacity. For shallower wells under 1,500m, the 150HP Workover Rig offers a more cost-effective solution.

FAQs

Q: What depth wells can this workover rig handle?
A: The 250HP workover rig is rated for well servicing operations up to approximately 3,600 meters depth, depending on tubing size and well conditions.

Q: What's the advantage of the 6×6 chassis over a 4×2?
A: The 6×6 off-road chassis provides significantly better traction on rough, muddy, or sandy access roads — critical for reaching remote well sites in desert or jungle environments where paved roads don't exist.

Q: Can I get a double drum drawworks on this rig?
A: Yes. Single drum and double drum configurations are both available. The double drum option adds an auxiliary line for sand line operations, fishing, and bailer work.

Q: What mast heights are available?
A: You can choose between a 21m or 23.5m two-section telescopic mast, depending on your well servicing requirements and tubing running needs.
